braced by longitudinal tie rods and spokes or drumis mounted in ahousing which directs the air stream coming from the linter brush andcarrying the lint and as the air passes through the screen like drum themajor portion of the lint is deposited upon the drum as it rotates andis collected on the roller at the rear side of the condenser.

rotate in a novel manner without the use of spokes, or longitudinal orradial braces, leaving the interior of the drum entirely open and thusmaking it possible to provide fixed shields within the, drum to directthe air current into a flared conduit, also located in the drum with theends of the drum sealed off so that the air may be confined and directedthrough a single outlet flue from which it may be conveyed away togetherwith the lintand the dirt contained therein to the end that the lint anddirt will not be permitted to dissipate into the gin room.

It is another object of the invention to provide a novel type ofcondenser which may be applied to a single gin or linter so that thelint being delivered from the gin may be condensed and the air ladenwith dust and foreign matter may be confined and entrapped and conveyedto a point outside of the room and the dust nuisance withinthe room thusabated.

The type of condenser herein described is specially adapted for use witha single linter thus conducing to a thinner bat of lint being depositedon the drum and facilitating the disposition of 50 the dust generated bythe linter; furthermore the lint produced by each linter can be moreuniformly regulated for each linter is provided with its one condenser.

Since the linter brush generating the air cur- 5 rent works against backpressure caused by the air having to pass through a bat of lint on thecondenser, if a single condenser is employed with ing from thecondenser. 0

By the use of a condenser of the type described with each linter it hasbeen found in practice With the above and other objects in view theinvention has particular relation to certain novel features ofconstruction, operation and arrange- 20 Figure 1 shows an end view ofthe condenser.

Referring now more particularly to' the drawwork and having at theirupper ends the cross 3 which may be made of wire mesh, but preferably ofperforated sheet metal. The ends of the drum may be secured to theannular angle irons 40 the periphery thereof radially outwardly project-The drum 5,

ing flanges la-4a, note particularly Fig. 3, and the foraminated drum orscreen 3 lies within the boundary of said flanges. Thus, any lintcollecting on the drum is out of the way of the internal gear teeth andthe flanges function not only to reinforce the ring but also insureagainst lint passing over the ends of the drum to said teeth.

A transverse shaft l0 extends through lower portion of the drum and ismounted in the inside bearings II, II fastened to the rear legs of theend supports I. This shaft gears l2 fixed and drive the ring gears 5thus rotating the drum on its supporting rollers 6. The outer end of theshaft ID has a sprocket wheel 13 fixed thereon over which a drivingsprocket chain may operate to rotate the shaft H3. Other driving meansfor the drum than that specifically hereinabove described may beemployed.

Above the drum there is a compression roller l4, preferably formed ofwood, which extends approximately from end to end of the drum. Thisroller is fixed on a central shaft l5 whose ends extend beyond theroller and are located in the vertical U-shaped bearings i6, 6, at theupper ends of the end castings 9. The ends of the roller i4 have themetal ferrules Ma, Ma having extended circular flanges I l-b, Mb whichroll on the tracks 4.

There are the roller supporting arms I1, I'I, whose upper ends arepivoted to the upper ends of the end castings 9 and the lower ends ofthese arms have the upwardly open bearings l8, 18, to receive the endsof the shaft I9 on which the bat receiving roller 20 is mounted. Thisroller cooperates with the drum 3 and is provided to receive thecompressed bat of lint 2i. The bat rolls about said roller 20 asindicated in Figures 1 and 2, the arm 11 permitting the roller 20 tomove outwardly from the drum as the roll enlarges. The roll of lint,when it reaches the desired size, may be removed and another roller 20replaced for the removed one.

As the lint leaves the linter, it is carried by the air current throughthe lint flue 22 to the drum. This flue is enlarged adjacent the forwardside of the condenser which is of a width approximately equal to thelength of the condenser and which extends upwardly to the compressionroller [4. It confines the lint to the forward or exposed area of thedrum 3. Within the drum there is fixed the housing 24, preferably formedof sheet metal and of a length substantially equal to the length of thedrum. This housing is of a frusto-conical form having its small end openand arranged close to the drum at one end with its larger, or discharge,end arranged at the lowest point of the drum and being there connectedto the outlet flue 25. 24 is provided with a longitudinal slot 26approximately parallel with the axis of the housing and arrangedopposite the lower portion of the There is a vertical partition 21 of alength of the drum 3 and extending side wall of the drum, opposite theroller Hi, to the upper margin of the slot 26. There is a skirt, orplatform, 28, also preferably formed of sheet metal and extending fromthe lower margin of the slot 26 forwardly to the inner wall of the drumand in approximate alignment with the bottom of the hood 23, the drum,as it rotates, thus moving betweentheadjacent confronting margins of thebottom of said hood and said skirt or apron.

in has the spur thereon which are in mesh with forming the hood 23 Theportions of the ends of the drum between the partition 21 and the hood23 are closed by the end plates 29, 29, suitably secured to theframework.

The air from the linter and carrying the lint cotton enters across theface of screen or drum uniformly distributed and deposits the lint onthe drum passing onwardly through the slot 28 into the housing 24 andthe air laden with dust, and a certain amount of fine lint, passes ontoward the large or outlet end of the housing and into the outlet flue25. Since the housing gradually enlarges toward its dicharge end morecapacity is provided for the constantly increasing amount of air to behandled and the dust carried into the confined area in front of thepartition 21 will gradually move downwardly until it is caught up by theair current from the conventional suction fan connected with the outletflue 25 and will becarried away thus preventing collection of dust orother foreign matter in the condenser. housing 24 declines toward itsoutlet end to facilitate the exit of the dust and foreign matter.

The ends of the housing 24 as well as the partition 21 and skirt 28 aresuitably anchored to the-end castings 9 and to the end cross bars 2 toprovide a rugged structure.

The drum rotates in the direction indicated by arrow in Figure 2. Thelint will be deposited, as above stated, in the form of a tion of thedrum inclosed by the bat will pass underneath the roller l4 and becompressed thereby and will move on to the roller 20 around which itwill be rolled until the roll has reached the required size. As the batpasses the roller l4, the air under compression from the linter brush aswell as the air suction from the fan will be out off from it.

The bat will thus be released from the drum and will be free toaccumulate on the roller 20.

A substantially closed conduit will thus be formed from the linter,through the condenser, to the point of discharge, thus preventing theescape of dust and free lint into the linter room.

By reason of the construction a completely inclosed condenser may beconnected with each linter so that the linter may operate as heretoforebut making it possible to collect all the air generated by the linterbrush after this air has deposited its lint on the drum or screen andonly the air coming from the brush is required to be handled.

The lint passing through the screen into the housing and out through thelint flue 25 may be collected and recovered.

It may be noted that the confined area defined by the partition 21, thehousing 24 and the skirt 28 is such that any dust collecting thereinwill be aided by gravity as well as by air suction in its movementtoward the discharge, that is to say, the skirt declines toward the slot26 and the axis of the housing 24 declines toward the point of exit andas is obvious the partition 21, is in an approximately vertical plane tothe end that there is no point in the confined area from which anymaterial will have to be lifted against the force of gravity. 7

The drawings and description disclose what is now considered to be apreferred form of the invention byway of illustration only, while thebroad principle of the invention will be defined by the appended claims.I
